Linas Vepstas d4ed8f8d1f Spidernet DMA coalescing
The current driver code performs 512 DMA mappings of a bunch of
32-byte ring descriptor structures. This is silly, as they are
all in contiguous memory. This patch changes the code to
dma_map_coherent() each rx/tx ring as a whole.

Linas Vepstas 66c097165c [PATCH] powerpc/cell spidernet variable name change
Cosmetic patch: give the variable holding the numer of descriptors
a more descriptive name, so to avoid confusion.

Jim Lewis 9b6b0b81f0 [PATCH] Spidernet: add ethtool -S (show statistics)
Add the ethtool -S (show statistics) feature to the Spidernet ethernet
driver.  I have tested it extensively and believe it is ready to be
applied.

Arnd Bergmann 11f1a52b87 [PATCH] spidernet: performance optimizations
Performance optimizations, changes in these areas:
  - RX and TX checksum offload
  - correct maximum MTU
  - don't use TX interrupts anymore, use a timer instead
  - remove some superfluous barriers
  - improve RX RAM full handling

Jens Osterkamp aaec0fab5f [PATCH] net: add driver for the NIC on Cell Blades
This patch adds a driver for a new 1000 Mbit ethernet NIC.  It is
integrated on the south bridge that is used for our Cell Blades.

The code gets the MAC address from the Open Firmware device tree, so it
won't compile on platforms other than ppc64.

This is the first public release, so I don't expect the first version to
get merged, but I'd aim for integration within the 2.6.13 time frame.
